Write a for statement to add all the numbers divisible by 3 or 5 between 1 and 1000.  (4) What is the output of the following code? Is there a relationship between the variables x and y? If yes, state the relationship? What is the output?  (4) int x = 19683;  int i; int y […]

What is the output of the following code? (4) for (int k = 2; k <= 10000;=”” k=”k” *=”” k) =””>cout < k=””>< “=”” “;=””> cout <> What is the output of the following C++ program segment? Assume all variables are properly declared. (4) for (j = 0; j < 8;=”” j11)=””> cout < j=””

Suppose that the input is 6 -2 4 9 -5 8. What is the output of the following code?  (4) int num, count, temp = 1; cin >> num; for (count = 1; count <= 4;=”” count++)=””>     temp = temp + temp * (num + count);     cin >> num; cout “temp=””> >

The following program contains errors that prevent it from compiling and/or running. Correct all such errors. (4) #include #using namespace sdt; const int LIMIT = 35; int main();     long long num1, num2:     double first, second;     cout >> “Enter two integers less than 100: “”     cin < num1=””>> num2;     cout >> endl;

What is the difference between a pretest loop and a posttest loop? (2, 4, 5) How many times will each of the following loops execute? What is the output in each case?  (5) a. x = 5;  y = 50;  do     x = x + 10;  while (x <>  cout < x=””>< “=”” “=””><

Write an input statement validation loop that prompts the user to enter a number less than 20 or greater than 75.   (2, 4, 5) Rewrite the following as a for loop. (2, 4) int i = 0, value = 0; while (i <= 20)=””>     if (i % 2 == 0 && i <=>         value

What is the output of the following program? (6, 7, 8) #include using namespace std; void compute(int x, int& y, int& z); int main()     int one = 7;     int two = 5;     int three = 6;     compute(one, two, three);    cout < one=””>< “,=”” “=””>< two=””>< “,=”” “=””>< three=””><>     compute(two, one, three);    cout <

What is the output of the following program? (6, 7, 8) include using namespace std; int temp; void sunny(int&, int); void cloudy(int, int&); int main() int num1 = 6; int num2 = 10; temp = 20; cout < num1=””>< “=”” “=””>< num2=””>< “=”” “=””>< temp=””><> sunny(num1, num2); cout < num1=””>< “=”” “=””>< num2=””>< “=”” “=””><

In the following program, number the marked statements to show the order in which they will execute (the logical order of execution).  Also what is the output if the input is 10? (6, 7, 8) #include using namespace std; int secret(int, int); void func(int x, int& y); int main()         int num1, num2; _____   num1 =

Consider the following program. (6, 7, 8) #include #include #include using namespace std; void trackVar(double& x, double y); int main()     double one, two;     cout < fixed=””>< showpoint=””><>     cout < “enter=”” two=”” numbers:=””>     cin >> one >> two;     cout <> trackVar(one, two);     cout     trackVar(two, one);     cout     return 0;
